IMPROVEMENT IN SLElGH-BELLS.

Specification forming part of Letters-Patent No. 183,605, dated October24, 1876; application iled September 18, 1876.

To all 'whom it may concern:

Be it known that I, GEORGE W. TUCKER, of Waterbury, in the county of.NeWiHaven and State of Connecticut, have invented an Improvement inSleigh-Bells, of which the following is a specification:

Sleigh-bells have been made of two hemispheres of sheet metal, unitedby'interlocking flanges at the edges, and the sheet metal has also beencontracted around a separate base, so as to employ a single piece ofsheet metal in addition to the separate base.

The object ofthe present invention is to obtain a sleigh-bell madeentirely of one piece of sheet metal, and at the same time to producemusical or resonant tonguesthat vibrate more freelyr and produce aclearer note than the sleigh-bells heretofore made.

I strikeup with dies a cup-shaped'blank having a rounded bottom, andperforate the same with a central hole for the rivet, and with'the'proper holes or openings to tone the bell and to give freedom tothe escape of the resonant vibrations from lthe inside of the bell, andI out the edges of the said cup into scallops shaped like a Gothic arch.There are three or more of these archshaped points at equal distancesaround the edge of the cup, and they are bent inward after the clapperof the bell has been placed in the cup. This bending operation isperformed in dies that close the metal down to the ,globular or othershape,lleaving the tongues at the proper distance from each other toformthe slots.

By this construction there are three or more (preferably four) tonguespointing toward each other, and they are' of hard, sonorous, andhomogeneous meta-l that vibrate by the contact of the chipper or ding,and these tongues give a clear tone and depth of vibration that it isimpossible to obtain from the bells heretofore mad e.

In the drawing, Figure l is a section of the cup. Fig. 2 is an exteriorview, with the metal perforated and cut out to form the arch-shapedpoints. Fig. 3 is a section of the complete bell, and Fig. 4 is an endView of the same.

The dies employed-are of ordinary character, shaped to accomplish thesuccessive operations, as well known to persons skilled in the art. n

After the cup-shaped blank of sheet metal has been drawn to the formshown in Fig. l, with the hemispherical base a and straight sides b, itis perforated at 2, for the attachingrivet c, Fig. 3, and with theopenings 4: for the passage of vibrations of air from the inside of thebell. The arch-shaped scallops d are also cut out in the cylinder b,after which the4 clapper or di'n'g e is inserted into the cup and thescallops d pressed toward each other by a hemispherical die that bendssaid points and closes them, leaving, however, slots between thevibrating points of the proper Width, or

lthese slots may be rendered true by rotary saws or files.

A bell made in this manner is a new and useful article of manufacture,that is superior to those heretofore constructed in the particu*- larshereinbefore named.

I claim as my invention- 1. A sleigh-bell made of one piece of sheetmetal, including the portion to which the attaching-rivet is applied, asset forth.

2. A sleigh-bell made of sheet metahhaving three or more vibratingtongues pointing toward each other with intervening slots,substantially' as set forth.

3. The method herein specified'of making sleigh-bells from a cup-shapedblank by cutting out the blank with arch-'shaped tongues, and bendingthose tongues toward each other for retaining the clapper, substantiallyas set forth.

Signed by me this 11th day of September,

GEO. W. TUCKER.
